TI-AM62x: Add Zephyr Support for M4 and R5 cores #49413

Closed DhruvaG2000 closed 1 year ago

DhruvaG2000 commented 1 year ago

Is this request related to a missing driver support for a particular hardware platform, SoC or board? Please describe. The R5 and M4 cores are MCU cores in the TI Sitara processor AM62x and it would greatly benefit having support for Zephyr on these cores. One could perhaps build the binaries on the main A53 core running linux and then flash them to the MCU cores using Remote Proc.

Describe why you are asking for this support? I am asking since I am not 100% sure on how to go about this effort, whether the port procedure would be different than other MCU's or not and also how and whether the code/OS running on the A53 core affects these other cores. Will we have to add support for things like RProc RPmesg, interrupts, etc. or this is taken care of completely by the linux side?

If this is a new board or SoC, please state whether you are willing to maintain the Zephyr support for it if it is included in the main tree This can be called as a new board, because the headers are the same as that of a Raspberry pi.

Another thought- This could perhaps be extended to the entire TI's KeyStone 3-ARCH ?
